title: [An epidemiological survey of snoring disease and OSAHS among 374 truck drivers in Guangzhou, China].
abstract: OBJECTIVE
  To investigate the prevalence rates of snoring disease and obstructive sleep apnea-hypopnea syndrome (OSAHS) and their risk factors among truck drivers in Guangzhou, China.
  
  
  METHODS
  A questionnaire survey was conducted in 374 truck drivers who were selected from 5 logistics companies in Guangzhou by cluster sampling. Those who had potential snoring disease or OSAHS underwent polysomnographic monitoring at night. The obtained data were analyzed to calculate the prevalence rates of snoring disease and OSAHS and determine the risk factors for OSAHS.
  
  
  RESULTS
  A total of 335 subjects completely questionnaires, with a response rate of 90%. Among the 335 subjects, 125 (37.3%) had habitual snoring, and 42 (12.5%) had OSAHS according to the diagnostic criterion (apnea-hypopnea index ≥ 5 times/h). The multiple stepwise regression analysis showed that the risk factors for OSAHS were age, alcohol use, family history of snoring, body mass index, and upper airway abnormality. Of the subjects with grade ≥ 2 snoring and OSAHS, 65.4% often felt sleepy when driving during daytime, and 42% had suffered or nearly suffered traffic accidents due to sleepiness when driving. Moreover, 95.5% (320) of the 335 truck drivers did not consider snoring a disease, and 98% did not think traffic accident might be related to snoring.
  
  
  CONCLUSIONS
  The prevalence rates of snoring disease and OSAHS among truck drivers are 37.3% and 12.5%, respectively. Therefore, prevention measures should be established according to the epidemiological characteristics to help the truck drivers realize the hazards of snoring disease and OSAHS, thus minimizing the prevalence and hazards of the diseases.
